ASRock Z77 Pro 3 - Reboot suddenly & lost Bios Boot options

[bododavid]

Hi

My friend has ASRock Z77 Pro 3 and he has One SSD 128GB in Sata III port and 2 Western Digital 1Gb in Sata II.
In SSD he has install Windows 10. Before one month he installs Windows 10...its fresh installation.

The problem now is that Suddenly pc shut down and then it cannot find SSD disk to boot.
I try to re-order in bios boot menu and then everything is ok.

Maybe it need to RestoreBios to default..... and also Reset CMOS?

Let you know also that when he change SSD from Sata III (1 port ) to Sata III (2port) also lost boot order and search to boot from
Sata II ports that are install Western Digital HDDs

I  think that he has latest Bios!
